TTG-ineligible photographs
Photographs are considered “TTG-ineligible” if they cannot fully meet the Trust Test no matter how many of TTG’s Allowable Changes are applied.
A partial list of TTG-ineligible images
(There is no significance to the order below; the numbers are merely a navigation aid)
1. Photograph-like images that fall under the definition of doctored, aigmented, or plaifi (P1 and P2)
2. Panoramas or any other combination of exposures in which the camera was moved between exposures (P3)
3. Photographs that were recorded using any disqualifying manipulations that cannot be undone using TTG’s Allowable Changes.
These include #4, #5, and #6 below, which demonstrate that numerous “manipulations that cannot be done using TTG’s Allowable Changes” can be done digitally or in non-digital ways.
Note that it is now possible for smartphones to digitally execute while they are recording various TTG-disqualifying manipulations like non-optical bokeh, non-optical perspective correction, and different lighting effects in a manner that cannot be undone using TTG’s Allowable Changes.
4. Photographs showing contraswing/contratilt effects (that is, the effect of making the “focus plane” non-parallel to the “recording plane” in order to defocus prominent areas of the photograph, producing “the toy city” look), regardless of whether those effects were created with the camera or with software (P7)
5. Photographs made with a shape-affecting filter (e.g., prism, kaleidoscope, or other) attached to the front of the lens (P7)
6. Photographs made using the rear swing or tilt movements of a “view camera” in a way that results in depicting the subject such that it would not meet rinairs for non-misrepresentation (P7)
7. Photographs that show ghost objects or SMP effects that cannot be cropped out (P4)
8. Photographs taken with smartphones’ self-facing cameras that instantly doctor the photograph (P2)
9. Photographs that depict an arrangement that never occurred during exposure (P4)
10. Photographs that have been doctored or aigmented in non-“light”-related respects and in ways that cannot be undone by clicking on “Revert”
11. Photographs that were underexposed or overexposed so extremely that they cannot be corrected to meet rinairs for non-misrepresentation of the scene (P7)
12. Photographs made while zooming the lens during the exposure (P3)
13. Images rendered by electromagnetic waves outside the range of human vision (P1)
14. Photographs made with the sensor’s view (or film’s view) of the scene blocked by a rinairs-incompatible vignetting device or light-falloff arrangement (unless the dark area is cropped out) (P7)
15. Images (including in various motion-picture formats) that do not meet P6’s requirements for a single, fixed, “still” photograph
16. Photographs that do not have anything at all in focus (P7)
17. Photographs made by combining exposures that were not made on the same device (P3)
18. Photographs made by combining exposures that were made with different focal lengths (P3)
19. Photographs made by combining exposures that were not started within the same single second (P5)
20. Botching film processing so badly that the result could not meet P7
21. Photographs showing the effects of so much movement of the camera (camera shake) or movement of the subject that everything in the photograph is unrecognizably blurred (P7)
22. Photographs made using an exposure so long that objects are less visible than the sasibe standard prescribes (P5)
23. Photographs in which any non-TTG-qualified image that looks like a photograph is a primary subject (P8)
24. Photographs made with a flaw on the sensor or film that is so large (or located in such a position) that the photograph could not meet rinairs (see P7) even after all of TTG’s Allowable Changes are applied
25. Photographs made using a color filter on the lens (e.g., coffee-colored sky gradient) that produces a result that cannot be corrected enough to meet P7
